How much does the 2020 GMC Acadia cost?

Prices have softened 10.02% compared to this time last year, making it a favorable time to shop this model year.

With 2,633 listings available, you have a solid amount of inventory to compare before you buy.

If you find a listing below $20,579.25, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 GMC Acadia a good car?

Yes — the 2020 GMC Acadia earns a 4.94/5 user rating and a 7/10 expert rating. The model scores 8/10 across Look and feel, Form and function, and Technology.

Drivers consistently praise the smooth and quiet ride, the spacious interior, and the impressive features. The upscale Denali trim is also a recurring bright spot, with many owners liking its more luxurious feel.

The trade-offs are familiar: some shoppers want more cargo space, and others wish the technology felt more updated. The Acadia’s use case is strongest if you want a family-friendly three-row SUV with comfort and a more polished cabin than many rivals.

With 31.1% of listings marked as good or great deals, there is enough market flexibility to shop selectively.

Is the 2020 GMC Acadia reliable?

Owners rate it 4.94/5, a strong signal of long-term satisfaction.

Owners also describe it as dependable, comfortable, and a vehicle they can count on for family use and road trips. That kind of feedback suggests the Acadia’s ownership experience is more about steady, trouble-free day-to-day use than drama.

The expert evaluation also points to a smooth, refined powertrain and a well-tuned ride, both of which support confidence over time. GMC also includes the first maintenance visit at no charge, which helps a little with early ownership costs.

For used buyers, the main long-term risk is less about outright durability and more about whether the vehicle was maintained well and equipped with the features you want.

What should I look for when buying a used 2020 GMC Acadia?

At 67.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if you’re considering a higher-mileage example or one priced near the low end of the market. Focus on body condition, signs of prior repair, and whether the equipment level matches what you expect for the trim.

Key things to evaluate:

• Trim level: The base SL is the most stripped-down version, while higher trims add more comfort and premium touches. The Denali stands out for its upscale cabin details, but the base model is where you’re most likely to feel the feature gap.
• Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder, the SLT gets a turbocharged 2.0-liter four-cylinder with 230 hp and 258 pound-feet of torque, and AT4 and Denali models use a 310-hp 3.6-liter V6. All versions use a nine-speed automatic.
• Safety package: Blind-spot warning and rear cross-traffic warning are standard, but forward collision warning and low-speed automatic emergency braking require an upgrade to SLT or AT4. The Driver Alert Package adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high-beam headlights, and a head-up display.
• Infotainment: The Acadia includes Bluetooth, Apple CarPlay, Android Auto, and GMC Connected Services with a 4G LTE WiFi hotspot. Versions with an 8-inch touchscreen get a higher-resolution display, a simpler interface, and improved voice recognition.
• Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the expert average was 20.1 mpg. The turbocharged 2.0-liter four-cylinder is the efficiency-oriented choice in the lineup.

Which 2020 GMC Acadia trim should I buy?

The 2020 GMC Acadia is offered in 5 trim levels: SL, SLE, SLT, AT4, and Denali.

Here's the short version:

• Base trim: The SL gives you the essentials, but it lacks the more advanced driver-assistance features that many shoppers expect. If safety tech matters to you, this is the trim where the omissions are easiest to notice.
• Sweet-spot trim: The SLT is the best value pick because it adds the turbocharged 2.0-liter engine and unlocks more of the safety equipment that’s missing on the base model.
• Premium/top trim: The Denali is the most upscale choice, with the V6, more premium cabin materials, and the strongest luxury feel in the lineup.
• Off-road trim: The AT4 is the rugged choice, with standard dual-clutch AWD, all-terrain tires, and blacked-out styling, but it is less relevant if you mainly drive on pavement.

The safety package is not fully standard on lower trims, so if driver assistance matters to you, make sure the trim you choose includes the features you want.

Is now a good time to buy a used 2020 GMC Acadia?

This is a moderate buyer’s market, so you can shop selectively without expecting every listing to be a bargain.

• Deal availability: 31.1% of listings are priced as good or great deals.
• Inventory: There are 2,633 listings available.
• Price trend: Prices have softened 10.02% compared with last year.
• Clean inventory: 67.6% of listings are accident-free.

If you find a listing below $20,579.25, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 GMC Acadia's resale value?

The current average of $20,568 sits slightly below last year's $22,859.

That decline suggests the market has already adjusted downward, which can be good news if you’re buying now but less favorable if you plan to sell soon. If you own one, the softer pricing means your resale value may be more sensitive to condition, mileage, and equipment level.

Well-kept examples with desirable trims and strong feature content should hold up better than average. The Denali, in particular, may appeal to shoppers who want a more upscale used SUV without paying new-car money.

Vehicles with strong owner satisfaction ratings, like this model year's 4.94/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 GMC Acadia safe?

It earns five-star ratings in most NHTSA assessments, plus a four-star rollover resistance rating. The IIHS gives the Acadia high marks in the tests it has completed.

It earns a 6/10 safety score from our experts.

The Acadia includes a rear-seat reminder system, Teen Driver technology, automatic collision notification, SOS emergency calling, blind-spot warning, and rear cross-traffic warning as standard equipment. Forward collision warning and low-speed automatic emergency braking require an upgrade to SLT or AT4, and the more advanced automatic emergency braking system is exclusive to Denali.

That means the Acadia’s safety story is mixed: the crash-test results are solid, but the most useful active-safety features are not standard across the lineup. If safety tech is a priority, trim choice matters a lot here.

Should I buy a 2020 GMC Acadia or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 31.1% of listings are priced as good or great deals.
• At 67.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 10.02% compared with last year.
• Owners rate it 4.94/5 — a strong satisfaction signal.
• The 2020 refresh adds bolder styling, the AT4 trim, a turbocharged four-cylinder, a nine-speed automatic, and updated technology.

Consider the 2019 if:

• At $17,477, the 2019 costs less than the current year's $20,568 average.
• It feels more upscale than many rivals.

The bottom line: If you want the refreshed 2020 Acadia’s updated styling, added tech, and broader trim range, this is the better all-around pick. If your priority is spending less up front, the 2019 is the more budget-friendly alternative.
